WPW1 series intelligent air circuit breakers (hereinafter called ACB) are applied for the network circuit of AC 50Hz, rated voltage 400V, 690V and rated current between 630A and 6300A. Mainly used for distributing energy and protecting the circuit and power supply device against short-circuit, undervoltage, single-phase ground fault, etc. The ACB has intelligent protection function and the key parts adopt intelligent release. The release can make the accurate selective protection, which can avoid cutting off the power and improve the reliability of power supply.
The products conform with IEC60947-1,IEC60947-2 standards.

WPQ2 series automatic transfer switch is the best development of the company generation products. Mostly used to monitor the power supply circuits. When main power failured, it will change over to backup power by automatically, thus completing the transformation of power system . At present, in particular suited for the important electricity power places where disallow to failure, in order to meet the needs of the scene. Automatic switch has self-input and self-recover,self-input without self-recover, utility to utility, utility-generators work with variety functions, the product applied in 220V,AC 50Hz,rated current from 10A to 1250A (CB class) automatically switch products.

1. Adopt the double row type composite contact,side pull institutions, micro motor prestore and microelectronics control technology, come true zero flashover (no arcing chamber).
2. Reliable electrical and mechanical interlocking chain, the implement of the components indepen dently with islation switch, the use of safe and reliable.
